The Endangered Species Print Project has a clever approach to conservation: a series of limited-edition prints depicting endangered species, with the number of prints correlating with the number of individuals left in the wild. For this sunlight-saturated Panamanian Golden Frog by Jenny Kendler, that's a wild population/print run of only 100. All the proceeds from print sales go to Project Golden Frog. (For other species, proceeds go to a conservation group helping that particular species).
Thanks. Now I know what I want for my birthday (birthday gifts are allowed to be frivolous, and I have enough socks for now).
I hope they come out with a book with prints of all those animals. :)
